Big contracts can change a player’s life—but sometimes, they change a little too much. Whether it was a dip in performance, a sudden attitude shift, or a newfound obsession with their “brand,” these guys let the money talk a little louder than their bats.
These aren’t just overpaid players—they’re stars who acted like they’d already punched their Hall of Fame ticket the moment the ink dried. From clubhouse divas to disappearing acts, these 15 players reminded us that money might buy a mansion, but it doesn’t always buy humility.
15. Jason Heyward

Heyward cashed in big after a strong season and a strong reputation—but never quite lived up to the hype. His bat went quiet while his paycheck kept screaming.
14. Yoenis Céspedes

Once the Mets backed up the Brinks truck, Céspedes seemingly started prioritizing everything but baseball. Golf injuries, wild disappearances—his contract years felt more like a reality show.
13. Josh Hamilton

Hamilton’s story was already dramatic, and the massive deal with the Angels added another wild chapter. Expectations were sky-high, but his production plummeted just as fast as his discipline.
12. Jacoby Ellsbury

The Yankees paid big, and Ellsbury basically vanished into thin air. For years, fans wondered if he was still on the roster—or on a beach somewhere spending his millions.
11. B.J. Upton

After signing a big deal with the Braves, Upton transformed from a solid outfielder into one of the league’s biggest mysteries. The swagger stayed, but the swing didn’t.
10. Barry Zito

Zito went from Cy Young winner to San Francisco’s most expensive enigma. His contract felt like an anchor, dragging his performance down for years.
9. Pablo Sandoval

The “Kung Fu Panda” got a fat contract—and then, well, just got fat. His time in Boston was more about waistlines than win totals.
8. Carl Crawford

Crawford was a speedster who got a megadeal and promptly lost his spark. Injuries and inconsistency turned that contract into a cautionary tale.
7. Chris Davis

Davis hit bombs, got paid, and then forgot how to hit altogether. His contract became the punchline of every Orioles conversation for years.
6. Miguel Cabrera

Yes, Miggy is an all-time great—but after he got the mega-extension, the production dipped while the paycheck stayed elite. He earned his money early, but the later years were rough.
5. Alex Rodriguez

A-Rod always had talent, but once he got those monster deals, the ego ballooned. From scandals to suspensions, it felt like the money only fueled the drama.
4. Albert Pujols

Pujols was a legend in St. Louis, but after his massive Angels contract, he never quite looked the same. The numbers dipped, the legs slowed, and the contract loomed large.
3. Matt Kemp

Kemp got paid like a superstar and started acting like one—even when his performance didn’t back it up. Injuries and inconsistency followed him around after the payday.

2. Prince Fielder

Fielder signed a huge deal and brought big expectations, but his bat never quite matched the billing. Health issues cut his career short, but that contract still felt like a swing and a miss.

1. Bryce Harper

Harper leaned into the superstar image the moment he got paid, embracing the spotlight like it was part of the deal. He’s delivered big moments—but the ego definitely showed up just as loud as the bat.
